20090281653 | METHOD FOR FORMING A BACK-TO-BACK WAFER BATCH TO BE POSITIONED IN A PROCESS BOOT, AND HANDLING SYSTEM FOR FORMING THE BTB WAFER BATCH - The invention relates to a method of forming stacks of wafers to be doped one-sided, in particular solar wafers, for loading a process boat with batches of wafers, where a predetermined even number of wafers is serially provided in reception slots of a transfer carrier to be clamped in a horizontal plane with an upward facing stacking opening. For increasing the packaging density and hence for increasing the throughput of the diffusion process one half of the number of the wafers provided serially in the transfer carrier is transferred out of the transfer carrier in the form of a first wafer stack in a mounted standby position located outside of the transfer carrier, then the other half of the number of wafers serially provided in the transfer carrier is moved out of the transfer carrier in the form of a second wafer stack and the second wafer stack is swiveled in a manner that the wafers of the second wafer stack reach a position swiveled by 180° in relation to the position of the wafers of the first wafer stack in its standby position, and subsequently the second wafer stack is transferred to the standby position of the first wafer stack, aligned to it and then joined together as form fitting with the first wafer stack to a form a package-like Back-To-Back wafer batch (BTB wafer batch) by respectively abutting against each other simultaneously and congruently the sides not to be doped of the wafers of the first and the second wafer stack associated to each other, whereupon the BTB wafer batch is picked up as form fitting by a transfer gripper and loaded into the process boat. | 11-12-2009 |
20100121477 | METHOD FOR POSITIONING AND/OR GUIDING AT LEAST ONE ARBITRARY PROCESS HEAD FOR THE METALLIZATION OF THIN SUBSTRATES AT A DEFINED DISTANCE ABOVE THE SUBSTRATE SURFACE - A method for positioning or guiding at least one arbitrary print head or a printing unit having at least one pressure nozzle for the imprinting of thin substrates such as wafers at a defined distance above the surface of the substrate, which is to be provided on a support like a paddle or printing table. Distance sensors continuously acquired distance measurements to the surface of the substrate which is to be imprinted. An adjustment of the print head up to 6 degrees of freedom is ensured by actuators in such a manner that the section of the opening of the pressure nozzle of the print head can be adjusted so as to be coplanar to the section of the surface of the substrate which is to be imprinted. The print head is thus maintained or readjusted so as to adjust the section of the opening of the pressure nozzle of the print head to the surface of the substrate which is to be positioned on the support table so as to be coplanar and so as to maintain the coplanar position during the printing process. | 05-13-2010 |

20110308691 | METHOD AND DEVICE FOR FORMING A PACKET-LIKE BACK-TO-BACK WAFER BATCH - Method and device for forming a packet-like back-to-back wafer batch made up of a predetermined even number of wafers that are to be doped on one side. The wafers of one half of the batch are horizontally and congruously arranged on supporting surfaces of a support system which are disposed at a vertical distance from each other. Holding elements of a holding system have a horizontal upper holding surface and a horizontal lower surface and are provided so as to be movable back and forth relative to two adjacent supporting surfaces between a releasing position and a holding position. The wafers of the second half of the batch, which have previously been moved into a position that is offset by 180° relative to the position of the wafers of the first half are inserted into a holding system so each wafer of the second half rests on the horizontal upper holding surface. Each holding element is simultaneously moved outward in the horizontal direction relative to the adjacent supporting surfaces until the horizontal upper holding surface is in the releasing position and the wafer of the second half rests on the wafer of the first half in a suspended manner on the formed air cushion. Each holding element is moved inward in the horizontal direction into the holding position, in which the horizontal lower surface of the holding element fixes the two wafers. | 12-22-2011 |
